Abstract: As imaging technology advances, one of the unavoidable part of image processing is the image enhancement. Image enhancement is to improve the visual quality for specific applications. The ...

Revealing mechanisms underpinning cell function requires understanding the relationship between different biochemical reactions in living cells. However, our capabilities to monitor more than two ...

Presented here is a MATLAB-based program for image compression using discrete cosine transform technique. It works for both coloured and grayscale images. Over the last few years, messaging apps like ...

Audio frequencies range from 20Hz to 20kHz but these frequencies are not heard in the same way. Frequencies below 20Hz and above 20kHz are very difficult to hear, while those not much more than 20Hz, ...
